Specification of Letters Patent.

Patented July 25, 1916.

Original application filed October 6, 1913, Serial No. 793,545. Divided and this application filed March 29,-

To all whom it may concern: I i

Be it known that I, ABRAHAM GERsTnN- ZANG, a-citizen of the United States, and a resident of the borough of the Bronx, county of Bronx, city and State of New York, have lnvented a certain new and useful Tooth- Brush, of which the following is a specifica-' tion. I

This is a division of my application for patent filed October 6, 1913, Serial No. 793,545. a

The object I have in view is the production of an entirely portable and satisfactory tooth brush. 7

Further objects are to produce a brush, which may be firmly held in the hand while in use, and in which the handle may be cleansed.

A further object is to increase the facility of removal from the carrying case.

These and further objects will more fully appear from the following specification and accompanying drawings, considered together or separately.

In the drawings, Figure 1 is a plan view of a brush embodying my invention in collapsed form and located within a carrying case; Fig. 2 is a side view of the same, portions of the brush and the case being shown in section; Fig. 3 is an elevation of a brush in extended position; and Fig. l is a sectional View of the same.

In all views like parts are designated by the same reference characters.

The brush illustrated is formed of a body 1 made of any material. The body is preferably made with a short length of handle section and a back portion, to which the bristles are attached, oifset relatively to the handle section so that the latter will be in line with the longitudinal center of the brush, as a whole. By this construction the compactness of the device will be increased. In connection with the body is a handle 2. This handle is collapsible, it being made telescopic for this purpose. It comprises a plurality of frusto-conioal sections 8. These sections may be nested one with another as shown in Fig. 2 in which event the tooth brush will be sufliciently short to go within a casing a of smallsize. The handle may be extended as shown in Figs. 3 and 4, in which event the handle will be long enough and rigid enough for use. To assist in the security of connection of the sections, they Serial No. 17,585.

may be screw-threaded as shown in Fig. 4. In order to make the brush more effective with a handle of limited length, the freeend section is provided with a curvature 4: so that the thumb of one hand may be applied to it and'the brush manipulated with greater steadiness than without it. Also to permit the cleansing of the handle, the end section is left open as shown. To assist in thewithdrawal' of the brush from the casing a it is provided with a'notch 5 to permit the introductionof the finger nail of the user. The olfset of the body 1 is of such extent that none of the frusto-conical members will be capable of passing over the body, thereby preventing removal of the said parts in the direction of the body of the brush. The parts will be prevented from being separated by movement in the other direction by reason of the fact that the inner end of each section is of less diameter than the outer end of the adjoining section. By this construc tion the frusto-conical members are always open thus providing means for keeping the brush in a sanitary condition.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention may be carried out in other ways.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A tooth brush having a back, a range of bristles, ahandle section offset relatively to the back, and a movable member engaging the handle section, said member and section being in line with the longitudinal center of the brush, the lateral dimensions of the handle section and member being less than a lateral dimension of the back and range of bristles.

2. A tooth brush having a back, a range of bristles, a handle section offset relatively to the back, and a plurality of movable members engaging the handle section, and one within another, said members and section being in line with the longitudinal center of the brush, the lateral dimensionsof the section and outside member being less than a lateral dimension of the range of bristles and the back.

3. A tooth brush having a back, a range of bristles, a handle section oli'set relatively to the back, a'plurality of movable members" engaging the handle section, and one Within another, said members and section being in line with the longitudinal center of the brush, and each of a diameter less than the lateral dimension of the back and bristles,"

and means for securing themembers together and to the section against movement in any direction.

4E, A tooth brush having aback, a range V of bristles extending longitudinally of and thread on the member and engaged by the thread on the section, a male thread on the opposite endfof the member, a second tubular member having'a female thread engaging the male thread on the first mentioned member, the diameter, of the second tubular 'member being less than the greatest lateral dimension of the range of bristlesand the back.

5. A tooth brushhaving a back, a range Copies of this'pate'nt may be obtained for ment in any direction.

of bristles, a handle section offset relatively to the back, a plurality of hollow, open ended movable members engaging the handle section and one Within the other, said members and section being in line With the longitudinalcenter of the brush, the diameters of the members being less than the lateral dimension of the back and bristles, and

fmeans for securing the members together a and to the section against movement 1n any direction.

6. A tooth brush having a back, a range of bristles, a handle section offset relatively to the back, a plurality of hollow, open ended, movable members I engaging the handle section and one withln the other,

,the outermost section having an are shaped notch in its extremity for engagement of the fingers, saidmembersand section being in line With: the longitudinahcenter ot' the brush, andmeans for securing the members together and to the section against move- This specification slgned and witnessed this 27th day of March, 1915.
